SpaceX, the company founded in 2002 by Elon Musk with the utopian dream of sending humans to Mars, became one of the world’s leading tech giants on Friday. The company, which specializes in launching rockets into space, communications satellites, and artificial intelligence, has made the biggest stock market debut in history. In the absence of an official listing, trading on the Nasdaq suggests a price of between $170 and $175 per share, up to 30% above the $135 at which the shares were sold. This valuation places the company at approximately $2.25 trillion, making it the sixth-largest company in the world by market capitalization. It was the largest initial public offering in history, ahead of Saudi oil giant Aramco’s 2019 debut, which raised about $29 billion.

Two months after NASA promised what seems impossible — to build the first human colony on the Moon within the next decade — officials at the U.S. space agency have outlined the first steps toward making that dream a reality. On Tuesday, NASA administrator Jared Isaacman announced that by the end of 2026, three robotic missions to the lunar surface will be launched, carried out by private companies.

Michael Burry, the fund manager on whom the film The Big Short (2015) was based and who became famous (and wealthy) for anticipating the subprime mortgage crisis, published on his blog in December 2025 his conviction that Tesla, Elon Musk’s electric vehicle and energy company, had been “ridiculously overvalued for a long time.” In his view, the company’s value to investors was only being diluted over time, in part by the exorbitant compensation paid to Musk, which does not match Tesla’s actual profits. Tesla’s stock has risen 115% over the past five years despite never having paid a dividend since its debut on the market a decade ago. Nearly six months have passed, but Burry’s thesis remains intact. In recent remarks he echoed a market rumor that Musk would use SpaceX’s initial public offering to merge it with Tesla, which would further dilute the value of a company that is currently the ninth-largest in the world by market capitalization ($1.64 trillion).

Stock markets continue to perform strongly despite the mounting risks. Neither the war in the Middle East, nor the resurgence of inflationary pressures, nor fears of an economic slowdown have managed to slow down the equity market. However, beneath this apparent strength there lies an increasingly evident fragility: the growing concentration of the market. The bulk of the gains rests on an increasingly limited number of stocks, and the trend is particularly evident in the U.S. According to Goldman Sachs, 85% of the S&P 500’s gains so far in 2026 (10%) come from technology. Excluding the sector, the advance drops to 3%.

Artificial intelligence (AI) is addicted to money. The major labs developing AI models are intoxicated with the dollars that will finance the technology’s evolution. The three leading companies in the sector, Anthropic, OpenAI and SpaceX, have announced in recent days plans to go public to raise more funds in an endless race. Other long-established tech multinationals such as Google, Microsoft, Meta and Amazon have also launched financial operations in what is shaping up to be the biggest capital raising effort in the sector’s history.
